Patent JP-H02106926-A (JP)
Title: Manufacture of semiconductor device
Inventor: YAGI ATSUO
IPC: H01L21/8238
Filed: 1988-10-17
Abstract: PURPOSE:To accurately control impurity doping even in low concentration by allowing a reinforcing board to adhere, and removing a semiconductor substrate from the opposite side to the reinforcing board adhering side by polishing to a predetermined thickness. CONSTITUTION:In an ion implanting step, since the ion implantation is conducted in a state that a semiconductor substrate 21 is sufficiently thick, the implantation having a peak at a relatively deep position can bs executed, and the depth peak position Rp from the surface can be set relatively accurately. Accordingly, implanting impurity concentration can be accurately controlled. Therefore, since the substrate 21 is removed by polishing to a thin film state after a reinforcing board 22 is applied, a P-well region and a N-well region can be formed in predetermined low concentration by applying, for example, to a C-MOS integrated circuit, and a MOS transistor is formed on the sufficiently thin substrate film. Thus, a semiconductor device having stable characteristics can be obtained.

Title: Spouting and jetting device for quick-tightening cylinder with cover
Inventor: STARK EMIL
IPC: A61F2/46
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To certainly eliminate dirt on surfaces of both a quick-tightening cylinder and a tightening pallet together with a bore emulsion getting into between them, by providing a spouting device making use of flow-acceleration of compressed air caused by reducing a cross section when air for cleaning is discharged. SOLUTION: A longitudinal hole leads from a compressed air connection part 11 to a lateral passage 12 for feeding a compressed air to both a longitudinal hole 13 and a nozzle 52. This distribution of supply of the compressed air can adjust the compressed air in a compressed air feeding system through variable adjustment of an effective cross section of the nozzle 52. When a quick- tightening cylinder 1 is released, a retracting nipple is moved upward so that an opening of a lateral hole is opened. Thereby, the compressed air from the lateral hole flows out, while an air pressure in the compressed air feeding system drastically drops. That is, just after a piston 5 moves the retracting nipple upward, a spouting hole 19 is opened so that the compressed air spouts out to perform cleaning.

Title: Driving work of foundation pile
Inventor: TAKEDA TSUTOMU
IPC: E02D7/00
Filed: 1984-12-10
Abstract: PURPOSE:To smoothly penetrate a foundation pile into the ground by penetrating a cylindrical foundation pile having a Y-shaped blade on its lower end into the stirred ground while being turned. CONSTITUTION:In driving a cylindrical foundation pile 7 having a Y-shaped blade 8 slightly longer than its radius on its lower end face, th ground is first stirred to a given depth by a stirring screw 6 and the screw 6 is taken out of the ground. Afterwards, the pile 7 with the blade 8 is penetrated into the stirred ground while being turned. Since the stirred soil goes into the pile 7 through the blade 8 in this case, the pile 7 can be smoothly penetrated into the ground without resistance.

Title: Method for monitoring station to be controlled
Inventor: TAMAI MASAYOSHI
IPC: H04L12/40
Filed: 1994-09-30
Abstract: PURPOSE: To automatically change the transmission interval of a communication test command to a station to be controlled corresponding to the state of the station to be controlled at the time of monitoring the normality of the station to be controlled by periodically transmitting the communication test command from a control station to the respective stations to be controlled and judging whether or not the response is returned within a prescribed time. CONSTITUTION: The station 2-1 to be controlled returns a first response message when it is not in a busy state at the time of receiving the communication test command from the control station 1 and returns a second response message when it is in the busy state. When no response is present, the control station 1 turns a test interval before transmitting the communication test command to the station 2-1 to be controlled next time to the time shorter than a time (a) when the response by the first response message is present and makes prompt detection possible. Also, as for the station 2-1 to be controlled from which the response by the second response message is present, the test interval before transmitting the communication test command to the station 2-1 to be controlled next time is made longer and the loads of the station 2-1 to be controlled are reduced.
